Abstract The Gas of the radon (Rn-222) can reach into the space of the houses in many ways, such as water supply, the emission from building materials, and the leakage through the soil. The aim of this study is determination of the concentrations of radon and uranium in ten soil samples of the sediment mud of houses' water tanks in Nineveh province, as well as ten soil samples have been taken from the same areas. This was achieved by using a technique of accounting the accumulative nuclear track on the detector LR-115, and by using the test tubes. The results indicated that the concentrations of the radon and uranium in the sediment mud were (4.98-40.555kBq.m3) & (0.35-2.83ppm) respectively, were as the values of soil samples were (1,44-58.84 kBq.m3) & (0.08-3.3ppm) respectively.
